Firefox 16+ and jQuery problem

I've been using Firefox 15 for a while now, for different reasons, but decided to update to FF 20 over a week ago. I realized then that some features on some pages didn't work as they used to.
I have a blog and one of my pages is a scrapbook, the code includes jQuery and isotope. It should do this when hovering over the images: http://media.tumblr.com/1645da372a86ad29161e70fdc47ecb1d/tumblr_inline_mjgfl6hrxf1qz4rgp.jpg
But it doesn't. It stays the same if you're using anything above FF 15, I checked with friends.

Is this a problem or is it how FF will be from now on? I went back to 15, but I'd like to be able to upgrade and that not only me and those with anything under FF 15 be able to see the site correctly.

Thanks!

There was a bug reported with the Isotope plugin in Firefox 19 (and 20 beta) when using CSS3 transitions. There is a way to force the use of jQuery, but I'm not familiar enough with this plugin to know where you put the code.

Now... that may well be a different issue than the one you've identified, but in order to figure out what's going on, I would need a simpler test case.

I do not know whether Isotope will be updated, or what changed in Firefox that is incompatible with Isotope.

Did you try changing your animationEngine setting linked above? I regret that I can't be more helpful with that, since I haven't used this library myself.
